Specification of Letters Iatent. Patntd 1 23, 7;

Application filed May 29, 1914. Serial No. 841,966.

tain newand useful Improvements in Order-- Guides, of which the following is a specification.

My invention relates to improvements in guides and has particular reference 'toaan improved devlce for- 1158111 the ordering of ophthalmic mountings. I V

The leading object of my invention is the provision of an improved guide for use in.

the placing of orders for ophthalmic mountings which will greatly lessen the laborattendant upon making out of the order; in that by reference to my improved guide certain arbitrary symbolstogether forming single number may be employedto denote the various measurements of the'mounting desired in place of it being necessaryto use a plurality of descriptive words accompanied by the various'measurements desired to be given.

A further object of my invention is the provision of'an improved order guide in a number descriptive of various styles of mountings and which shall also embodyex planatory matter indicating and setting out in detail the various points contained Wlllh in the number or comblnation of symbols.

Otherobjects and advantages of my im-' proved order guide should be readily apparent by reference to the following description taken in .connectionwith the. accompanying drawings, and it, will be'understood that I may make any modifications inthe specificvdetails of construction shown anddescribed within the scope of the appended claims without departing from or exceeding the spirit of'my invention.

The drawing represents a view of an order guide with three bridge size dimensions and other corresponding features," shown thereon, it being understood that in actual use a much greater variety of dimension numbers are ordinarily placed upon the'guide with corresponding information in the several following columns and the use and structural features of my orderguide in enlarged form"will ,be identical -with*that'liereinafter .describedi By reference to the drawing it will be noted thatjI have divided my guide into a number of columns numbered respectively as followszColunin No. 1 is entitled Dimension number, this column containing the serial number made up from; the various units in accordance with the accompanying explanation,

Column No. 2indicatesthe distance tween the" centers of the lenses; or what is commonly termed the 'pupilary distance size 0, size 00 and size 000 eye lenses. V

Column number 7 is employed to denote the he ght of the bridge being subdivided of the mounting, this same column 2 being subdivided into four partsgnumbers 3,1 4;; 5 and 6, serving 'respectively'to denote in millimeters the pupilary'dista'nce for size 1,

into subcolumns 8 and .9; denotingthe said height respectively in millimeters and insixteenths of an inch.

inclination of the bridge of the mounting Column number 10 serves to denote the from the plane of the lenses thereof. it being 1 subdivided intosubcolumns 11 and12 de- I noting 3 said measurements respectively in mlllimeters and in sixteenths of an inch.

Column No. 13 indicates the distance'be tweenithe inner edge of the lenses, 'or inf other words the width of bridge use noses of varying sizes. o Itisto be understood that-I donot in- (1 upon tend to limit myselfto the specific arrange ment illustrated and above described but that thepositi'ons of the columns may be varied andcertain of the sameeliminated or additional columns supplied as may prove desirable. 1 Y

As illustrated in addition to thevarious' columns above mentioned, a further explzu nation may be added as to just what constitutes the dimension or; serial number, the particular explanation reading as follows: T lie first figure O indicatesthe bridgeythe second figure'indicates' the pupilary distance; in sixteenths of an inch above two inches for 00 eye lenses; the third' figure indicates the height ofthe bridge 'insixteenthspand' thefourth'ligure"indicates the inclination of thebridgein sixteenths. I 1 i For example -let" it be assumed that the patients measurements have been'taken and it has been found that thepupil'ary distanceofthe patierit 58.75n1illimete1 s, that the noted by symbols other than the O.

i re distance between the inner edges oi the lenses as indicated in column 13 is 18.75 millimeters, and that the height and inclination of the bridge are 3 and 3, respectively, the 3 and 3 designating the height and inclination of the bridge beyond a horizontal and vertical meridian in sixteenths of an inch. T he person taking; the measurements refers to the horizontal row of figures in the guide and locates the row having all of the measurements mentioned contained therein, and when such row has been located it will be apparent that it is only necessary to reiter to the first column of figures designated at the top Dimension number which in the instance mentioned reads 0533, the 0 designating a narrow bridge, the 5 designating the pupilary distance between the lenses of 2 inches, or 18.75 millimeters, and the two remaining figures designating in siX teenths of an inch the height and inclination oi the bridge respectively. It is to be understood that other characters in place of the 0 may be used to designate other styles of bridges, the present chart being made out especially for bridges of a narrow construction.

In the first column of figures designatedl)imension number the 0 is an arbitrary symbol used to denote a specific construction of bridge, different styles of bridges being de- The second number indicates the pupilary distance in sixteenths of an inch over the arbitrarily fixed standard of two inches between the lenses. The third number indicates the height of the bridge in sixteenths oi an inch above the arbitrarily fixed standard of a horizontal meridian. The fourth number indicates the inclinationof the bridge in sixteenths of an inch over the arbitrarily fixed standard of a vertical meridian.

It will be only necessary to locate the column having" the distance between the lenses corresponding with the patients measurements. Then read horizontally across the column until the pupilary distance is reached, and then by reference to the upper portion of said column read the standard size of lens needed, the four standard sizes of lenses being designated 1. O, 00 and 000, respectively, and it will be seen that in this instance a 00 lens would be required.

From the foregoing description, the construction and purpose of my improved order chart should be readily apparent and it will be seen that l have provided a dimension or serial number for use in the ordering of mountings comprised of an arbitrary symbol. used to denote the style of the bridge, an; other symbol denoting; the excess or" the punilary width of the mounting over an arbitrarily fixed standard, and other symbols denotingthe variation. of other-symbols of the mounting over other arbitrarily tired standards, the actual measurements indicated by the various units in the dimension or serial number, etc., be ng pointed out n the columns following the column containing the dimension number and in the further xplanation printed therebelow. lt will thus be seen that by the use of my improved order chart one may readily make out an order for a number of mountings each of aditlerent size with a minimum amount oi labor and at the same time definitely and accurately bring-out in such way as to be clearly understood the various dimensions of each or" the mountings desired.

:I claim:

1. As an article of manufacture, an order card for ophthalmic mountings, comprising a series of columns having the variable .di-' mensions oi different ophthalmic mountings arranged in di ierent rows in the columns each row containing the dimension for a particularmounting, and an additional column containing; an order number composed the variable dimensions of certain of the other columns in the corresponding row expressed as anumber.

As an article oi manufacture, an order card for use in the purchase of ophthalmic mountings, comprising a plurality of consecutive columns bearing rows. of dimension numbers extending in alinement across the several columns and an additional col umn bearing; a dimension number formed by arbitrary selection of certain symbols or their equivalent from predetermined 5columns in the row. 7 v i 3. As article of manufacture, an order card for use in purchase of ophthalmic mountings, comprisi g a series of main columns, means for deer iatingthe particular essen al measurement of anfophthalmic mounting to be found in the respective columns, certain of said columns being" subdivided to contain the same measurement in different standards of measure, and one of the additional columns being subdivided into a plurality of minor columns suitably desie'nated'and bearing means to indicate possible dimensional variations in the complete ophthalmic mounting attainable in con-. nection with a standard center by the selection of the variable member indicated at the top or" such minor columns, and an additional major column bearing a dimension number built up from the several main dimensional columns to indicate the particular measurement of ophthalmic mountings necessary to fulfil the required conditions.
